My latest article in the Metapsychology of Liberation series is up at Phalanx. You can see it here: https://phalx.com/2016/09/10/contra-misanthropy-the-meaning-of-peace-a-metapsychology-of-liberation-part-2/
Quite often, when an esoteric view is expressed, the listener hears a universalist statement. We must define our terms carefully in order to clarify the point.
Universalism is the view that all religious and spiritual modalities wind up at the same salvation in the end, regardless of differences and distinctions in character or application. This is popularly expressed as “all religions are basically the same” or, with somewhat more sophistication, “all paths lead to the same goal.”
Esoterism is a focus on the way in which any given religion or spiritual modality may be turned inward upon itself so that the individual practitioner may also turn inward upon himself. Esoterism is the sum of mysticism, gnosis, and magic—what the author of Meditations on the Tarot refers to as Hermetic philosophy or what Schuon calls Perennial Philosophy or Traditional Metaphysics.
Esoterism states that the possibility of inwardness exists in principle in any authentic religious or spiritual tradition while acknowledging that it is more difficult to access in some than in others, sometimes considerably so to the point of practical impossibility. A religion may be called spiritually alive insofar as this possibility is actualized in the persons of living representatives of that tradition.
An esoterist will certainly focus on the practice of a particular tradition but, unlike the purely exoteric (outward) religionist, will not be uncomfortable with taking lessons from or even engaging in the practices of a genuinely living religion or spiritual tradition. What works, works. To put it more concretely: A Yogi who has, even for the briefest moment, touched the feet of God will feel no discomfort in the magical application of the Psalms. Game recognize game.
